TELEPHONE ATTACHMENT:

To all whom it may concern:

Be it known thatI, D JACOB DANIEL, a citizen of the United States, residing at Little Rock, in the county of Pulaski and {State of Arkansas, have invented certain new and useful Improvements in Telephone A ttachments,-of which the following is a full, clear, and exact description, reference being had to the accompanying drawings,

forming a part hereof.

My invention has relation to improvements in telephone attachments; and it consists in the novel features of construction more fully set forth in the specification and pointed out in the claim.

In the drawings, Figure l is a side elevaton of a telephone, showing the application of my invention; Fig. 2 is an enlarged front face elevation of the attachment; Fig. 3 is a vertical cross-section on the line 33 of Fig. 2; Fig. 4 isa horizontal cross-section on the line 4-4 of Fig. 2; Fig. 5 is a front face elevation of the attachment, with the slide or cover removed; and Fig. 6 is a detail of a section of the web or tape.

The object of my invention is to provide an attachment which may be removably secured to the mouth-piece of the ordinary telephone transmitter, said attachment being provided with a web mounted on a roll from which it may be periodically unwound across the edge of the mouth piece and thereby serve not only to protect the lips of the speaker against contact with the mouthpiece, but the said web may, in addition, carry a suitable calendar, the dates of which are exposed to the view of the person speaking into the transmitter, or the web may carry suitable advertising matter or both according to circumstances. The web is preferably impregnated with any suitable germ-proof and germicidal composition known to the trade, so as to serve as a sanitary membrane directly receiving the sound waves from the mouth of the speaker.

The advantages of the invention will be best apparent from a detailed description thereof, which is as follows:

Referring to the drawings, 1 represents an ordinary telephone transmitter and 2 the usual flarin mouth-piece thereof. Adapted to be passec over the walls of the mouthpiece at a point slightly rearward of the free edge thereof, is a plate 3, the plate having cut therefrom a substantially U-shaped opening U, the edges of the opening span- Specification of Letters Patent. Application filed August 19, 1914. Serial No. 857,525.

Patented July 20, 1 9151 ning substantially one-half of the peripheral wall of the mouth-piece. The friction'between. the sides or fork-arms 3', 3, thus carvedout of theplate, is sufiicient to hold the attachment to the mouth-piece. Formed integrallywith said arms 3, 3, and directed outwardly, are flanges- 4, 4, which are pro vided with marginal lips 5, 5, the flanges .4, 4, serving to'span the sides of the mouthpiece as shown and extending slightly be yond the outer edgethereof. The plate 3, p

which, together with its arms 3', 3, forms a saddle adapted to be passed over the mouth piece,is carried by, or is formed integrally with, a casing 6 which serves as a housing for aroll of paper' or equivalent aseptic and sanitary'web or tape w, on which is printed any, convenient form of calendar C, between successive dates of which maybe distributed advertising matter A, as shown. The open,

top of the casing is closed by a sliding cover 7, which is received between the flanges 4, 4,

aforesaid, and between the edge of the mouth-piece and the lips 5, 5, as clearly seen from the drawings. One end of the slide or cover 7 is provided with a finger-hold 8, by

which it may be readily manipulated, and

with side limiting lugs 9, 9. The formations 4, 5, serve as grooves or ways for the slide 7, and when the slide is inserted into the ways it is limited in one direction by the lugs 9 which come in contact with the casing wall. When the slide is fully inserted the inner edge 6 thereof projects a suitable distance beyond the terminals of the forks 3, 3, and of the flanges 4, 4, and serves as a cutting edge for the web to passed between the slide and the edge of the mouth-piece.

The operation will now be readily understood, and is substantially as follows: The attachment is first frictionally secured to the mouth-piece 2, by passing the saddle 3, 8, 3, thereover as described, after which the roll R formed by the web to is deposited in the casing 6, a suficient sectionof the web being unwound to span the opening of the mouth-piece. Thereupon the slide or cover 7 is slipped into place to cover the casing and protect the web, the cover being provided with suitable openings 0, O, for

the exposure of the printed matter on the web, the opening 0 coming opposite the center of the mouth-piece, that being the point fore the speaker when talking into the mouth-piece. The advertising matter A likewise comes well within the range of observation of the speaker, so that the web performs the function herein ascribed to it. By impregnating the web with suitable antiseptic and germ-destroying composition, the mouth-piece is rendered absolutely sanitary. At the end of each day, the web is pulled out or advanced sufiiciently to expose a new calendar day through the opening 0, and a fresh advertisement through the opening 9', the portion of the web pulled out being severed along the cutting edge e and discarded.

The details of the attachment may of course be changed in many particulars without departing from the nature of the invention. It may be stated in passing that the friction between the web 10 and the inner face of the slide 7, is sufficient to maintain the web taut at all times.

Having described my invention, What I claim is:

In combination with the mouth-piece of a telephone transmitter, a plate having a cut-away portion and side arms adapted to frictionally embrace the sides and the in- Gopies of this patent may be obtained for tel-mediate peripheral portion of the walls of the mouth-piece, suitable flange formations provided 'withn'iarginal lips formed with the side arms aforesaid, said flanges projecting beyond the edge of the mouthpiece, a casing at one end of the plate for the housing of a tape-roll, a slide operating between the flanges, and between the lips thereof and the edge of the mouth-piece, and normally extending slightly beyond the flanges and plate at the end opposite the casing whereby a cutting edge is formed, the tape from the roll being adapted to be directed between the slide and the edge of the mouth-piece, and be drawn across the opening of the mouth-piece, the slide having an opening opposite the mouth-piece to expose the tape to the eye, and the opening of the mouth-piece to the mouth, of the speaker, the parts operating substantially as, and for the purpose set forth.

In testimony whereof I affix my signature, in presence of two witnesses.
